Composer on Laptop and Monitor

Composer is the Windows® application used to program Radius, Prism, Edge, and Solus NX DSPs. In addition to the programming of one to many Symetrix DSPs, Composer also natively configures the setup and routing for Symetrix Dante I/O Expanders along with select third party Dante endpoints. Integrators can design a complete end-to-end DSP signal path with just one application.

Composer is “open architecture” meaning that choices of audio signal routings, DSP modules, and control signal processing are at the sole discretion of the programmer. This allows each system installed to perfectly match the requirements as well as adapt and expand as the system evolves or functional needs change. All classes of audio processing modules for signal shaping are provided including, but not limited to Mixers, Automixers, Matrixes, Equalizers, Filters, Compressor/Limiters, Automatic Gain Control (AGC), automatic ambient sound pressure level response (SPL Computer), and Feedback Fighters. Application-specific modules like the Room Combiners specifically address difficult integration issues such as automatically linking wall panels in combined spaces while specialized processes such as Acoustic Echo Cancellation (AEC) eliminate echo loops in conferencing applications.

Logic-based processing modules called Control Modules can be assembled in various combinations to elegantly overcome unique application challenges often encountered during system design. Commonly used Control Modules are Gates (AND, OR, XOR), Flip-Flops, Binary Encoders/Decoders, Multiplexers, and Delays. Logic chains may be driven by internal audio or logic signals, or external devices via RS-232, RS-485, or general purpose inputs. Logic chains can be used to trigger other internal logic functions, recall presets, drive general purpose outputs or send strings via RS-232, UDP/IP or TCP/IP for simple control of external devices such as projectors, screens, and curtains.

Composer also manages all control aspects of the system including 1000 Presets, Controller Numbers for assignment to Symetrix Wall Panels, web-based control interfaces, and 3rd party control via RS-232, UDP/IP, and TCP/IP. Presets may be recalled by time and date using Composer’s Event Scheduler and custom user interfaces called Control Screens can be quickly authored using WYSIWYG methods.

Control Screens are useful for technicians and consultants during commissioning as a means to consolidate commonly adjusted parameters from many units and modules into a set of easily accessible screens. They are particularly useful for end users when exported to SymVue, a network-based runtime application that runs on standard Windows PCs, including those touchscreen enabled, and tablets. SymVue can connect to any number of Symetrix DSPs and includes password protection to govern access to the control interface. Multiple instances of SymVue can be deployed across a control network and parameter changes are always in sync between Composer, ARC Wall Panels, ARC-WEB, 3rd party controllers, and SymVue.

Composer 5.5 release contains these updates:

  • An issue was resolved that caused audio dropouts on xIn 4, xIO 4×4, and xOut 4 Dante-enabled Analog I/O Expander devices after remaining powered on for an extended time.
  • An issue was resolved that sometimes caused sites with Attero Tech third-party Dante devices to not push.
  • Various minor issues have been resolved.
